Actor-network theory, which is considered as a development of socio-technical structuralism school, observes reservation and stability of networks containing personal and impersonal components such as individuals, organizations, communication software and hardware, and infrastructural standards by examination of socio-technical dimensions concurrently.The goal of this research is studying the i...

Online Social Networking may be a way to support health professionals' need for continuous learning through interaction with peers and experts. Understanding and evaluating such learning is important but difficult, and Social Network Analysis (SNA) offers a solution. This paper demonstrates how SNA can be used to study levels of participation as well as the patterns of interactions that take pl...

Earthquakes are one of the most destructive natural phenomena which consist of rapid vibrations of rock near the earth’s surface. Because of their unpredictable occurrence and enormous capacity of destruction, they have brought fear to mankind since ancient times. Usually the earthquake acceleration is noted from the equipment in crisp or exact form. But in actual practice those data may not be...

an important problem in performance evaluations of irrigation systems is the difficulty of the determining share of structural and operational elements and determining improvement solutions. in most studies, the combined impact of structural and operational elements on the performance of irrigation systems is assessed. some researchers try to separate the effects of structural and operational e...

A collection of networks is considered a network ensemble if its members originate from a common natural or technical process such as repeated measurements, replication and mutation, or massive parallelism, possibly under varying conditions. We propose a spectral approach to identify structural trends, i. e. prevalent patterns of connectivity, in an ensemble by delineating classes of networks w...

Identifying and quantifying dissimilarities among graphs is a fundamental and challenging problem of practical importance in many fields of science. Current methods of network comparison are limited to extract only partial information or are computationally very demanding. Here we propose an efficient and precise measure for network comparison, which is based on quantifying differences among di...

In this fMRI study, we explore the connectivity among brain regions in a shape-from-motion task using the causal mapping analysis of structural equation modeling (SEM). An important distinction of our approach is that we have adapted SEM from its traditional role in confirmatory analysis to provide utility as an exploratory mapping technique. Our current approaches include (I) detecting brain r...

RÉSUMÉ — Endogamie structurale et le réseau graphe de parenté Cet article, qui fait partie d'une série, aborde les thèmes du mariage et de la parenté sous un angle cinétique et structural qui déplace le centre d'intérêt, du point de vue initial, fait de modèles de règles, de terminologies, d'attitudes et de normes, vers l'exploration de relations concrètes dans une population, que l'on analyse ...
